The original holotype is composed of a partial dentary and seven teeth (two which are incomplete).[2] The holotypes for other species of this genus are solely represented by isolated molars. Shuotherium, along with Pseudotribos has been placed in the family Shuotheriidae as a sister taxon of the Australosphenida (see, Yinotheria),[4] making it a relative of modern monotremes. However, some studies place it and other shuothereres as closer to therian mammals,[5][6] and another outside of Mammalia altogether.[7]
